This invention relates to certain new and useful improvements in icescoring machines and more particularly to an improvement on my patentfor Ice scoring machine granted May 10, 1932,

No. 1,857,894, the object being to provide means for scoring the cakesof ice longitudinally at their longitudinal centers or to each side ofthe longitudinal center in order to increase the sections whereby thecake can be divided into a greater number of sections of equal volume,the construction being exceedingly simple whereby it can be readilyshifted to longitudinally score the cake of ice at the center'or toscore it to each side of the center.

Another object of my invention is to provide novel means for adjustingthe horizontally disposed saws on the vertically disposed arbors wherebythese saws can be readily positioned on the arbor and held in thatposition to either 20 form a single longitudinal score or a doublelongitudinal score in the sides of the cake of ice.

Another object of my invention is to provide a construction which can bereadily used in connection with an ice scoring machine as disclosed inmy above referred to patent, which is provided with feed mechanism forfeeding a cake of ice into the frame so that as the cake is moved intothe frame longitudinal scores can be formed in the sides of the cake andafter the cake has transverse scores can be formed in the sides of thecake in order to divide the cake into a plurality of sections of equalvolume.

While I have shown and described my improved construction oflongitudinal scoring means applied to a machine as disclosed in mypatent granted May 10, 1932, No. 1,857,894, I wish it to be clearlyunderstood that my invention is capable of being used with various typesof scoring machines which are provided with means for forminglongitudinal scores in the opposing sides of the cake of ice as itpasses through the machine and therefore I do not wish to limit myselfto the use of my improved construction of longitudinal scoring means toany particular type of machine as I am aware that it can be readily usedin connection, as for example, with a Uline ice scoring machine as nowbeing manufactured.

Other and further objects and advantages of the invention will behereinafter set forth and the novel features thereof defined by theappended claims.

In the drawings I have illustrated in a broad way the mechanism-foroperating an ice scoring machine constructed in accordance with myinvention using a portion of the structure disclosed in my Patent No.1,857,894.

In the drawings I indicates a frame through which travels feed mechanism2 constructed substantially the same as shown in my patent, said feedmechanism being adapted to feed a cake of ice into the frame so as tocut longitudinal scores on the sides of the cake of ice and to positionthe cake of ice within the frame so as to cut transverse scores on theice.

The transverse scoring means comprises a pair of saw arbors 3 and 4provided with a'plurality of saws 5 and 6, said arbors being mounted inbearings arranged within slides 1 and 8 at one end, which slides aremounted on guide rods 9 and are connected to an endless chain Yl0passing around sprocket wheels HandV l2. The opposite ends of the arbors3 and 4 are mounted in bear- I mounted on guide rods I6. f The boxes I3and I4 surround vertical shafts I1 and I8 on which are Vsplined beveledgears I9 and 23, which mesh with beveled gears 2I and 22 carriedrespectively by the saw arbors 3 and 4 whereby these arbors will berotated.

These boxes have a connection with an endless chain 23 working oversprocket wheels 24 and 25 Yso that as one arbor is 4moved upwardly toform a plurality of transverse scores in the t side of the cake of ice,the other-arbor-will be moved downwardly to form a series of transversescores in the opposite side of the cake of ice, the chains being driven`by suitable driving means in connection with timing mechanism whichcontrols the feed mechanism whereby when the cake is properly positionedafterhaving its longitudinal scores formed in the sides of the ice, thetransverse scoring arbors willV be moved vertically so as to formtransverse scores in the sides of the cake of ice.

The particularconstruction of driving means for operating thetransverse'scoring means forms no part of my invention and the abovedescription is given so that the operation of my improved constructionYof longitudinal scoring means will be clearly understood. v

V'The upper end of the shafts I1 and I8 are provided with beveled gears26 and 21, which mesh VVwith beveled gears 28 and 29 carried by ahorizontal shaft 30 Yprovided with a sprocketV Wheel'3I Vover whichVpasses a chain 32 which passes over a sprocket 33 fixed on the driveshaft 34 of an electric motor 35 whereby the horizontally disposedarbors 3 and 4 carrying the plurality of saws for forming the transversescoring Y bearings 39 at their upper ends, the upper ends carrying gears40 which mesh with intermediate gears 4|.;whch in turn mesh with gears42 carried respectively by the shafts I1 and I8,'whereby the verticallydisposed arbors 36 and 31'will shafts I1 and I8, gears 40, 4I'and 42. Y.

- The arbors `35 and 31 are formed exactly alike and the description ofone will be suflicientV for both, each arbor being formed with aplurality of grooves 43 which receive tongues 44 of sectional hubs 45and 46, which are provided with scoring saws 41 and 48. The hubs 45 and46 are provided'with collars 43 and 50 through which the bolts 49a passfor clamping the saws 41 and 48 in position between the sections and thevsections together whereby the saws can be readily inserted and removed.

' Fixed on each arbor adjacent its lower end is 'larY ange`55 formed onthe lower end of a sleeve 56 which is carried by the hub 45 whereby atelescopic connection is formed between the two saws. A second stop 51is carried by the arborV above the saw 48 and is adapted to be engagedby the hub 45 whenV moved down into position shown in Figure 6 at thesame time the hub 46 engages the stop'5l whereby the tWo Vhorizontallydisposed scoringV sraws'areV in position to form Vparallel scores toeach side of the longitudinal center of the cakes of ice.

V'Ifhe upper hub 45 is provided witha collar` 58 having aninternalflange 59 at its upper end engaging an annular flange 60 on a sleeve 6Iloosely mounted on the arbor and provided with a rack 62 which engages agear 63 carried by a shaft 64 which is provided witha crank arm 65having a spring pressed pin 66 which is adapted to engage an opening 61formed in a plate 63 carried by the frame I of the machine whereby uponrotation of the shaft 64 the two saws 41 and 48 can be raised andlowered in position so as to form a single score or a double score inthe side of the cake of ice.

In the drawings I have failed to show a ball bearing connection betweenthe sleeve 6I and collar 58 and I Wish to reserveY the right to use aball bearing at the junction of these two members.

In the operation of an ice scoring machine constructed in accordancewith my invention when it is desired to form a single scorelongitudinally in the sides of the` cake of ice in the centerY of thecake, theV saws are adjusted in the position shown in Figure 5 with theupper saw 41 approxmately Vone inch above the top of the cake of ice. Asthe cake of ice is movedY by the feeding mechanism of the machine intothe machine it passes the saws 48 which form longitudinal scoresV on thesides of the cake of ice along the center line. The movement of the cakeis then arrested by the feeding mechanism and through suitable timingmechanism Vas fully disclosed in my patent, the transverse scoring meansare set in operation so that the arbors 3 and 4 travel up and down thesides of the cake of ice orgin other words, as one arbor goes Vup, theother goes down so as to form transverse scores in the sides of the ice.This divides the cake of ice into sections of equal volume.

When it is desired to increase the number oi sections,` the crank 65 isoperated Yso as to lower the upper saw 41 and the lower saw 48V into theposition shown in Figure 6 and as thecake of ,j

ice is moved by the feeding mechanism into the Y machine, a pair ofscores are formed in the side of cake of ice to each side ofV itslongitudinal center whereby the cake will be divided into a greaternumber of sections of equal volume.

Thisprovides means for converting an ordinary construction of icescoring machine which is only capable of forming a cake Yof'ice with acertain number of sections into a machine which is capable of forming acake of ice into a greater number of sections by merely operating aVcrank, the construction being such that the saws are readily adjustedandheld in adjusted position so as'to form the desired numberof scores inthe sides ofthe cake of ice without rany danger g of these saws movingwhen in operation out of Y their'adjusted position.

The scoring saws arerpreferably formed in sections as shown in Figure 8in order to allow'the'se Y saws to be placed in, position upon'thearbors i or removed therefrom without dismantling the machine.

While in the drawings tain details of construction in forming thevertical saw arbors for forming the longitudinal 75` Y I haveillustrated 'cer-v is'cores vand the particular manner of .mounting thesame and adjusting the same, I wish it to be Lclearly understood that Ido not wish -to limit myself to any particular means for mounting andadjusting these horizontal saws on the vertically -disposed saw arborsfor forming the longitudinal scores as my invention consists broadly inproviding an ice scoring machine with a pair of arbors one arranged toeach side of a frame through which a cake of ice is adapted to pass,each arbor having more than one horizontally 'disposed saw slidablymounted thereon with means for adjusting said saws into position on saidarbors whereby one or more of said saws can be positioned to cut one ormore vscores in the sides of the cake of ice as it passes through themachine. While I have only shown two saws o-n each arbor, it is, ofcourse, understood that these arbors can be provided with two or moresaws which are adjustably mounted thereon whereby a number oflongitudinal scores could be formed in the sidesof the cake of ice as itmoves through the machine.

In the embodiment of my invention as herein shown, I have onlyillustrated two saws, one of which is always in position to form alongitudinal score on the cake of ice and the other of which is normallyout of position to form a longitudinal score in the cake of ice, saidsaws being capable of being adjusted on the respective arbors wherebythey can be brought into contact with the cake of ice independently orsimultaneously for increasing. the nmnber of sections of equal volume.

From the foregoing description it will be apparent that my improvedconstruction of longitudinal scoring means is capable of being used withother types of scoring machines than what is herein shown, therefore Ido not wish to limit myself to the use of any particular construction ofscoring means so long as means is provided for moving a cake of ice pastthe scoring saws.

The construction herein shown and described provides novel means forpositioning the saws on the arbors and holding said saws in adjustedposition and while I have shown certain details of construction, I amaware that various changes can be made without departing from the spiritof my invention.

The plate 68 is provided with two openings 61 to receive the pin 66 ofthe crank 65 when in its adjusted positions, whereby when the crank isoperated to position the saw 48 at the center of the cake of ice, thepin 66 will enter one opening. and hold the saw 48 at the center of thecake nf ice and the saw 41 above the cake of ice. When the crank isadjusted to lower the saws 41 and 48 into the position shown in Figure 6so as to cut parallel scores in the cake of ice to each side of thecenter, the pin 66 of the crank will enter the other opening of theplate 68 and hold these two saws in this position whereby the saws arelocked in their adjusted position to prevent any danger of their beingdisplaced when in operation.
